As an example, when the boundary line of the fitting sphere 410 and the boundary line of the sliding member 420 are displaced from each other by a predetermined angle, the separation of the fitting sphere 410 may be limited to the sliding member 420, but When the boundary line of 410 and the boundary line of the sliding member 420 coincide with each other, there is a problem in that the fitting sphere 410 is naturally separated regardless of the intention of the operator. Accordingly, when the sliding member 420 is interconnected via the connecting portion 432, the sliding member 420 forms an integrated structure, so even if the boundary line of the fitting sphere 410 and the boundary line of the sliding member 420 coincide with each other, the fitting hole It becomes possible to fundamentally solve the problem that the 410 is separated regardless of the intention of the operator. In particular, in the case of the branching part 120, since it is manufactured as a single product without separate or connected parts, and the fire-fighting top-down sprinkler head 200 is installed at a predetermined interval, if you want to install a bearing, the fire-fighting top-down sprinkler head 200 and It is possible only at both ends of the branching part 120 due to interference. However, if the detachable hanger unit 400 is applied as in the present invention, it is possible to install the hanger unit 400 at any position of the branching part 120, so it can be applied regardless of the installation location. very convenient in

Referring to FIGS. 1 and 2 , the fire detection sensor 500 is a general detection means, and in this embodiment, each branch unit 120 is individually installed to detect heat generated during a fire, and the control unit 900 ) to output each.

The branching part 120 is rotated. In addition, the solenoid valve 700 is operated so that the fire water is transferred along the fire pipe 100 to be sprayed through the fire-fighting top-down sprinkler head 200 and the spray nozzle 300 . In addition, it serves to control the operation so that the pin spot 800 is turned on. As an example, the control unit 900 receives a fire detection signal from each fire detection sensor 500 and compares it with a preset value to determine whether to rotate the branch pipe 120 clockwise or counterclockwise. , To explain this in more detail, as shown in FIG. 5A , when fire detection signals are sequentially output from the left and input to the control unit 900 , the control unit 900 determines that a fire has occurred on the left side, and the branching unit The rotation unit 600 is controlled to rotate 120 in a counterclockwise direction. On the other hand, when a fire detection signal is input from the fire detection sensor 500 located on the left and in the middle, but no fire detection signal is input from the fire detection sensor 500 located on the right side, the control unit 900 is Except for the branch pipe 120, the operation control of the corresponding rotation unit 600 is performed so that only the left and middle branch pipes 120 are rotated.

5A to 5C are diagrams for explaining the different operations of the fire evacuation guide mechanism for fire evacuation according to the present invention, which will be described with reference to the following.

Referring to FIG. 5A, when a fire occurs while the fire detection sensor 500 is installed in each branch 120, the fire detection sensor 500 located on the left detects it first, and then The fire detection sensor 500 located in the middle detects and outputs a fire detection signal to the control unit 900 .

For reference, since the fire detection sensor 500 located on the right does not detect any fire, it maintains its initial state.

The control unit 900 receives the fire detection signal from the fire detection sensor 500 located on the left and middle, compares it with a preset value, determines that the left side is the ignition point, and determines that the left side is the ignition point based on the signal reception order. 120) is operated to control the rotation unit 600 so that it rotates counterclockwise to rotate the branch part 120 in which the corresponding fire detection sensor 500 is installed, and by rotation of the branch part 120, a fire-fighting top-down sprinkler head (200) is inclined at a predetermined angle.

In addition, the control unit 900 controls the operation of the solenoid valve 700 and the pin spot 800, respectively, and the solenoid valve 700 is operated and controlled by the control unit 900 to open the supply unit 110, As the supply unit 110 is opened, fire water is discharged through the top-down sprinkler head 200 for firefighting through the branch unit 120 to quickly extinguish the fire.

In particular, as the firefighting water is discharged in a state where the firefighting top-down sprinkler head 200 is inclined at a predetermined angle, the indoor space is divided by the discharged firefighting water, and a water wall is naturally formed, thereby preventing the spread of fire and burns. It can provide some protection for evacuees from the dangers of

Furthermore, as shown in FIG. 6B , when the fire detection sensor 500 installed in each branch unit 120 detects all fires and outputs a fire detection signal to the control unit 900 , the control unit 900 controls a preset The value is compared to determine whether to rotate the branch unit 120 clockwise or counterclockwise. For example, if it is determined to rotate the branching part 120 in the counterclockwise direction, the control unit 900 operates and controls each rotation unit 600 so that all the branching parts 120 are rotated in the counterclockwise direction, and the branching part By the rotation of 120, the fire-fighting top-down sprinkler head 200 suppresses the fire while discharging the fire water in a state inclined at a predetermined angle.

As the firefighting water is sprayed at a predetermined angle, a water wall is naturally formed as the indoor space is partitioned by the firefighting water, thereby preventing the spread of fire and protecting evacuees from the risk of burns to some extent.

In addition, as the fire water discharged from the top-down sprinkler head 200 for firefighting is also sprayed on the ceiling (C), it is possible to prevent the flame from spreading to the ceiling, thereby having an incidental effect of preventing the spread of fire.

On the other hand, when the pin spot 800 is operated in a state in which the mist-type fire water is discharged from the spray nozzle 300, the light irradiated from the pin spot 800 is scattered while passing through the fog-type fire water. It will look prominent, and people around you can see the protrusion and figure out an evacuation route, so you can expect a quick escape.

Furthermore, when light is irradiated in a state where the pin spot 800 is inclined, a long illumination light is displayed on the floor. Since the evacuation route can be easily identified, there is an advantage in that rapid movement is possible.

Although the present invention has been described in detail only with respect to the specific embodiments described, it is natural for those skilled in the art that various changes and modifications can be made within the technical spirit of the present invention, and it is natural that such variations and modifications belong to the appended claims.
